DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0007] Referring to FIGS. from 1 through 3, a motion toy bird 10 isshown comprising a head 11, body 21, two wings 31, and two legs 41.

[0008] The head 11 comprises a bottom coupling hole 12, an upper beak13, a lower beak 14, a beak driving mechanism 15, and a spring 16. Theupper beak 13 is fixedly connected to the head 11. The lower beak 14 hasa middle part pivoted to the head 11, and a sector gear 141 fixedlydisposed at the rear side thereof. The beak driving mechanism 15comprises a DC motor 151, a pinion 152 fixedly mounted on the motorshaft of the motor 151, and a gear wheel 153 meshed between the pinion152 and the sector gear 141 of the lower beak 14. By means ofcontrolling the forward/backward rotation of the DC motor 151, the lowerbeak 14 is alternatively moved up and down relative to the upper beak13. The spring 16 is connected between the rear side of the lower beak14 and a part inside the head 11 to hold the lower beak 14 closed on theupper beak 13.

[0009] The body 21 comprises a front coupling hole 22, two side slots 23at two opposite sides, a coupling neck 24, which couples the body 21 tothe head 11, a bird head driving mechanism 25, and an eccentric linkingmechanism 26. The coupling neck 24 comprises an upper disk 241 fixedlyfastened to the bottom coupling hole 12 of the head 11, a bottom disk243 connected to the upper disk 241 and revolvably coupled to the frontcoupling hole 22 of the body 21 for enabling the head 11 to be rotatedrelative to the body 21. The bird head driving mechanism 25 comprises aDC motor 251, a helical gear 252 fixedly mounted on the motor shaft ofthe DC motor 251, a transmission device 253, and a crank 257. Thetransmission device 253 comprises a bottom gear 254, and a top disk 255.The top disk 255 has an upright eccentric rod 256. The crank 257 has oneend coupled to the body 21, a rod 258 disposed at the other end andinserted into a slot 243 in the bottom disk 243, and an elongatedsliding slot 259 disposed on the middle and coupled to the uprighteccentric rod 256 of the top disk 255. The eccentric linking mechanism26 is mounted in the body 21, comprising a gear 261, a helical gear 263,two eccentric wheels 265, and two links 267. The gear 261 and thehelical gear 263 are fixedly mounted on a gear axle 262 for synchronousrotation. The eccentric wheels 265 are respectively eccentricallycoupled to the two ends of the gear axle 262. The links 267 each have acoupling hole 268 at one end. The other end of each of the links 267 isrespectively stopped at the periphery of each of the eccentric wheels265. The gear 261 is meshed with the helical gear 252 of the DC motor251. The helical gear 263 is meshed with the bottom gear 254 of thetransmission device 253.

[0010] The wings 31 each comprise a lug 32 respectively inserted throughthe side slots 23 of the body 21 and coupled to the coupling hole 268 ofeach of the links 267. When turning the eccentric linking mechanism 26,the links 267 are forced to move the wings 31 alternatively up and down.

[0011] The legs 41 are respectively connected to the body 21 at thebottom side, and supported on a base 50.

[0012] The toy bird produces a motion when operating the DC motors151;152.

[0013] When starting the motor 151 of the beak driving mechanism 15, thelower beak 14 is turned downwards and opened from the upper beak 13.When cutting off power supply from the motor 151, the spring power ofthe spring 16 immediately pulls the lower beak 14 to its former closeposition.

[0014] When starting the DC motor 251 of the bird head driving mechanism25, the helical gear 252 is driven to rotate the gear 261 of theeccentric linking mechanism 26, thereby causing the helical gear 263 torotate the bottom gear 354 of the transmission device 253. During rotarymotion of the bottom gear 354 of the transmission device 253, the crank257 is forced to rotate the disks 241;243 and the head 11, and at thesame time, the eccentric wheels 263 are rotated to move the links 267,causing the links 267 to turn the wings 31 up and down.

[0015] A music IC and programmable control circuit assembly (not shown)is installed in the body 21 or the base 50, and adapted to control theoperation of the motors 151;152, causing the toy bird 10 to move thehead 11, the lower beak 14, and the wings 31 when driving the music ICto produce sound.

[0016] Although a particular embodiment of the invention has beendescribed in detail for purposes of illustration, various modificationsand enhancements may be made without departing from the spirit and scopeof the invention.
